So the thread there is misleading. "Dan" the guy that initially said no rooted devices will get an upgrade, has no affiliation with Motorola. Matt, on the other hand, believes that unlocked devices may get the update if they revert to stock before sending the device in. He was quick to clarify his points and stated that he is asking for an official response through his channels at Motorola.
[Xoom Android Development] coolbho3000:
Updated with the L2 prefetching patch. This increases performance by a lot in many situations, notably Linpack for Android. :p Also uploaded the whole kernel to github. https://github.com/coolbho3k/Xoom-OC
[Xoom Android Development] nindoja:
I just rooted/flashed this all with no problems. Thanks for the great work!
[Xoom Android Development] techs1200:
Running v2 now :)

Nice work!
[Xoom Android Development] Flaunt77:
Can anyone rerun the benchmarks with v2 vs v1?

Man, if we can get the GPU oced a bit more as well we can stomp the qualcomm chips before they even come out.
[Xoom Android Development] p-slim:
If I'm not mistaken the bootloader is relockable. 2 motorola will have a hard time telling me there not putting MY HARDWARE in because of software I'm running on my tablet.
[Xoom Android Development] :
Amazing work sir! Over 3000 in quadrant and 63 mflops in Linpack vs 49 mflops with v1! Thanks for making my Xoom kick even more ass!
[Xoom Android Development] bishop72:
Now when I run the benchmark sometimes I am getting 1400 scores and when I run it again I get anywhere around 2300-2900 scores. Why is that?
[Xoom Android Development] p8ntballah21:
I have a question about the installation process, sorry if this is rather noobish. In step 2: where do I extract the files to? I'm assuming that it gets extracted to the tools folder in the sdk? Right? Also for I would assume that you would open up adb from the tools folder and that's where you type in step 3? I apologize for needing clarification lol.
[Xoom Android Development] alexdw369:
Now, I didn't know about the Google Services Framework part, but I have two listed. I did just as you said with Force Stop and Clear Data with both copies, and also with the market and rebooted. Opened Market, and got the client out-of-date message, and clicked OK. It has of yet made no attempt to download. I repeated this process on 3G only, just in case, you know... Still no luck :(

Edit: Finally gave in and re-unlocked it. Market was unresponsive for a few seconds, but somehow managed to update itself without me ever telling it to. And then after I tried installing some apps, it took about 3 minutes for the first one to start loading. After that, all was good. Any idea why the delay? I haven't noticed anyone else complain about this, but the day I brought my Xoom home, the delay in Market apps downloading almost had me returning it after 30 minutes...
[Xoom Android Development] zack_sparrow:
Niiiiiceeee work!
[Xoom Android Development] Elysian893:
Loaded v2 late last night, promptly got 3005 on Quadrant, very nice.
[Xoom Android Development] destroyerbmx:
I couldnt hold out any longer, took me 2 days to break down and root it, got v2 up and running

I hate how it did a data wipe, no need for that just trying to deter people from rooting
[Xoom Android Development] nitewalker033:
Works as advertised.... Thanks
[Xoom Android Development] destroyerbmx:
mine freezes and reboots everytime I push it to 1.5, I cant even squeeze in a benchmark before reboot
[Xoom Android Development] nswenson:
Maybe he can make another kernel with a little higher voltage. The current kernel patch has very little increase. I saw some other posts with some instability issues. The other option is of course to drop the speed down to 1.2 or 1.4 GHz.
[Xoom Android Development] jgrimberg1979:
Does anyone have a copy of the stock kernal so we can put it back to original condition?
[Xoom Android Development] ElephantGlue:
How is battery life with the new kernel? On my OG droid I saw increased battery life with some kernels even when OC'ed so I was just wondering..
[Xoom Android Development] Richie97:
EH, every Google Experience Device does it, don't they? Minor setback for an open bootloader.
[Xoom Android Development] ogar1978:
HD Video

Any chance the extra speed helps with HD video playback?
[Xoom Android Development] destroyerbmx:
I am interested in this too, I was just running at 1ghz and it reset out of nowhere
[Xoom Android Development] Elysian893:
The Droid didn't do a data wipe as far as I remember...
[Xoom Android Development] hawkye:
Nope it sure didn't for a couple of mine...
[Xoom Android Development] destroyerbmx:
I found out why it restarts, eventually it will override setcpu and run at 1.5 ghz which will eventually cause a crash
[Xoom Android Development] miphonematt:
#100 in Linpack

I clocked a 64.339 in Linpack which earned me the #100 spot in fastest tested Android devices! That is just TOOOO awesome. My Xoom is in the top 100 (just barely but still!)!!!

I was going through the recent scores, and it seems that someone knocked out a 65... wow. There are quite a few 64+ Xooms as well. This is just too cool, time to test out Quadrant now.
[Xoom Android Development] Richie97:
Droid didn't have fastboot, and it wasn't a true Google Experience device. Nexus One, Nexus S, etc are Google Experience Devices.
[Xoom Android Development] xlGmanlx:
I say SBC all day for this bad boi! This thing is so freak in awsome
[Xoom Android Development] destroyerbmx:
my xoom is resetting every hour, could we get a 1ghz kernel w/ pre cache enabled?

Setcpu might be the problem, but I m getting massive lag making it hard to type this
[Xoom Android Development] xlGmanlx:
I am oc'd to 1504 and not having any issues. I think that every device responds differently
[Xoom Android Development] Elysian893:
What browser are you using? Dolphin HD is pretty bad about text input lagging, I haven't used the stock browser to compare...
[Xoom Android Development] destroyerbmx:
I am using the stock one, I was editing the last post so that might be why it was so laggy as it was not laggy chatting on the FB app. Is there another app for setting cpu speed w/ this kenerl other than setcpu?
[Xoom Android Development] czonin:
65.088 #80 in Linpack
[Xoom Android Development] destroyerbmx:
I found cpu master will still set my clocks, I am running at 1.504 until it resets just to see what it is. I ve only rooted and flashed the kernel, I ve flashed 4 other phones so I dont think I did something wrong. When the stock kernel and system come out I will reflash back to stock and start again just to make sure if I am still having problems.
[Xoom Android Development] mrksbrd:
Me three...I want to see if I would have same f/c issues with either kernel
[Xoom Android Development] destroyerbmx:
I am having fc issues with apps like facebook and stuff, I just think that is 3.0, the resetting is the the oc, every time its at 1.5 it resets within 5 min, hope it isn't hurting the hw, I am not overheating
[Xoom Android Development] destroyerbmx:
For the freezing issue I found CPU master will hold the clocks so it won't oc on its own like setcpu allows
[Xoom Android Development] coolbho3000:
I cannot reproduce your issue. What exactly is happening? Were you on 2.1.1a? You must have posted several times in this thread. Describe it in one concise post and I'll take a look at it.

Koush ripped a stock boot.img a long time ago, soon after he posted the root method... It's hosted on kanged.net: http://mirror1.kanged.net/motorola/stingray/stockboot.img. If you want to rip your current one, run cat /dev/block/platform/sdhci-tegra.3/by-name/boot > /sdcard/boot.img

(Btw, yeah awesome, I write the overclock patch and you recommend a guy who stole my UI completely ;))

EDIT: Unless there's some major bug in 2.1.1a that's affecting some Xooms and not others (very unlikely), all the symptoms you're describing would come from using an old, pre-2.1.1 version with the Xoom. Since I update the Market and XDA versions almost simultaneously, that puts the source from which you got my app from into question. I'll increase voltages for 1.5GHz in the next version due to reports of instability such as yours regardless.

I also think I have a successful GPU overclock in place, but it's difficult to verify with benchmarks since there seems to be either a 30fps or 60fps cap on them, but never in between, based on current frame rate (some kind of vsync? I'm actually fairly certain it is vsync). Nenamark won't break 30.0 fps ever, for example, and fps2d shows the frame rate occasionally dipping heavily down to 30 fps.
[Xoom Android Development] bigrushdog:
coolbho3000 you are a beast sir! Just killing it!
[Xoom Android Development] destroyerbmx:
I was running the market app of setcpu, I donated, most current on market, but after using my xoom for about 2 hours the CPU would start running at 1.5 if I knew it was happening I could go into setcpu and reset it, the display in setcpu would not show 1.5, it would display 1.0 but still allow the CPU to run to 1.5, which in my case was causing it to reboot. I ran it at 1.5 until reset and it too about 5min, when the reset occurred I was at 31c which is not as high as I have seen it so I don't think its overheating, sometimes its just a freeze and I have to force reset which c ould be voltage or my CPU hates me

My computer had an ssd crash so I am not able to flash until tomorrow anyways, for now CPU maser will hold my clock settings and I am stable.
[Xoom Android Development] idkwhothatis123:
flashed stockboot.img and no wifi, gets error when enabled. obviously not rooted img, therefore no adb remount for pushing the bcm file. help? lol and btw, anyone having wake issues via power button? after a long time of dormant on this oc img, my device takes like 10 presses to wake
[Xoom Android Development] kinggroin:
Did you not read the part that said to unlock and root FIRST? Hopefully you get it figured out.
[Xoom Android Development] idkwhothatis123:
Holy sh*t you're a genius. :/ I'm no noob to android my friend. Anyways, anyone with legit advice is welcome to respond if you know what's going on lol. I've just reflashed the oc img and pushed the bcm file again. Wifi is fine. I think the wake up issue is either a weird issue with leaving it on wifi, dormant, and plugged in or its via the oc kernel. I'm gonna try adj the wifi setting to turn off when screen off. Ill attempt to figure it out.
[Xoom Android Development] destroyerbmx:
Since we are talking about wifi, any one else getting slow speeds? Slow to me is 3mbps when my fascinate is pulling 6.5 mbps on the same network. Also found out the galaxy s beat my xoom in gpu benchmark, unimpressed!
[Xoom Android Development] destroyerbmx:
I did the same thing, I tried to go back to stock and my wifi is broken now, looks like for the time being I have a $800 paper weight

I have tried so far, re-unlocking it, re-root, and reinstalling the kernels w/ wifi fixes and nothing has worked so far, still getting error under wifi.

DONT install the stock boot that was posted, it will get you back to a stock kernel at the expense of your wifi right now.

CPU master did not fix my issue either, I found out the kernel would override that too, but I have bigger problems right now, like the wifi.
[Xoom Android Development] destroyerbmx:
I did a million thing not sure, but the last thing I did was reinstall this kernel as per directions and my wifi came back.

Applying the wifi fix along with the stock.img did not work so I am not sure what the disconnect is maybe a dev will have time to look at in the future but its back to this kernel for now.

That was a good scare
[Xoom Android Development] nswenson:
Xoom is pushing more pixels around. You also need to factor in vsync caps. If max fps is capped to a lower level than galaxy s the benchmarks can be affected greatly. The OP mentioned vsync cap (30 fps if I remember correctly) affecting gpu benchmarks. Specs show Tegra2 is a good 20% faster than the sgx540 in the galaxy s.
[Xoom Android Development] FuzeAction:
Make sure that whatever speed testing method you are using, you are choosing the same server on each device.

I am able to pull 10mbps on both my xoom and my G2 when connected to my home network.

As far as your Galaxy S benchmarks, how does it fare in Linpack? My Xoom is right at 66MFLOPS. Linpack tests pure computational power, your Fascinate won't compare.
[Xoom Android Development] jkurl:
Can someone on here who has the OC kernel installed test out this custom boot animation and see if it will work w/ the OC Kernel.

http://www.xoomforums.com/forum/motorola-xoom-themes/563-my-first-xoom-boot-animation.html
[Xoom Android Development] youngproguru:
When you installed the over clocked kernel you also installed a new Wifi Module (Driver) that matched.

So, If you install reinstall the stock kernel you must also reinstall the stock WiFi driver. They are a set.

As you can see in the instructions:

QUOTED from installation instructions to install the OC Kernel:

1. Make sure you've unlocked your Xoom's bootloader for flashing first, then root it.

2. Grab this zip and extract it. It includes a boot.img with the overclocked kernel and a corresponding wifi module: http://www.setcpu.com/files/xoom_ocboot_v2.zip. Thanks to Koush for the rooted ramdisk in this boot.img!

3. Reboot into the bootloader by running:

adb reboot bootloader

4. Flash the boot image to your boot partition, then boot back into Android by running:

fastboot flash boot xoom_ocboot.img

fastboot reboot

5. Push the bcm4329.ko to your /system/lib/modules folder and reboot to re-enable wifi:

adb remount

adb push bcm4329.ko /system/lib/modules/bcm4329.ko

adb reboot

bcm4329.ko is the WiFi module modified for the new kernel. So, the stock would need to be replaced if you would like to return.
[Xoom Android Development] FuzeAction:
Come at me, Bro!

http://www.greenecomputing.com/apps/linpack/linpack-top-10/

I told my SO that I have the fastest benchmarked Xoom in the world. Can you believe she didn't care?

Knock me off my pedestal before I post it in my signature.
[Xoom Android Development] cruiserbax:
Not exactly. Linpack tests only floating point operations for the java compiler and these resalts vary greatly depending on software like JIT. If you want to compare two devices for raw processing power at the core without having any software factor in run Nbench on both and compare those numbers. It takes 10 minutes to run but it will give a much more fair comparison as to the raw procoessing power of the two devices. Of course the tagra 2 will blow the hummingbird to little sad peices even on one core, untill we get a decent multi-core capable benchmark then.... Even more sad littler pieces.
[Xoom Android Development] FuzeAction:
I humbly bow to your superior knowledge of benchmarking tools and processing capability.

Thanks for enlightening me!
[Xoom Android Development] destroyerbmx:
I will run ncore, does anyone have the stock wifi driver module for wifi?

http://db.tt/Wvgz1sT

as stock as i gets..straight from my Xoom dump
[Xoom Android Development] destroyerbmx:
can someone confirm that this is all I need to get the stock wifi back up, I had the issue last night and after flash maddness I finally got it back working. I dont want to go to stock unless I am sure I can get my wifi back up
[Xoom Android Development] ejlax:
i had to do this a couple times when I tried to flash the zImage from the tiamat kernel...I went back to this a few times. This reeally should be all you need. Well that and the stock boot.I mg...;)
[Xoom Android Development] destroyerbmx:
it worked just as you said, heres the process incase anyone else wants to do this

Stock Kernel http://mirror1.kanged.net/motorola/stingray/stockboot.img Thank you Koush

Stock bcm4329.ko http://db.tt/Wvgz1sT Thank you ejlax

adb reboot bootloader

fastboot flash boot stockboot.img

fastboot flash boot rootboot.img

fastboot reboot

adb remount

adb push bcm4329.ko /system/lib/modules/bcm4329.ko

adb reboot

You might not have to flash the rootboot again but I was not able to mount r/w access to push the original wifi driver.
[Xoom Android Development] kjdocs:
link to stockboot.img is dead.

Anyone have mirror?
[Xoom Android Development] almostinsane:
Worked for me this AM.

Installed this and immediately had endless reboots @ 1.5. 1.4 works fine but I don't notice and increase in speed. The UI is still a little jerky flipping between screens.
[Xoom Android Development] almostinsane:
Ok, after using it for a day I flashed back to stock. Had way to many FC's even with it at stock speeds and couldn't see any difference with it OC'd.
[Xoom Android Development] joeski27:
Well I'm not sure what is going on with this kernel. After updating to 3.0.1, then unlocking, then rooting, I went through the procedure for flashing this kernel just as I had done last week. I was able to successfully send the xoom_ocboot.img, then rebooted in fastboot, then remounted, then pushed the bcm4329.ko kernel (verified afterwards by looking with Root Explorer), then rebooted in adb, but the kernel didn't take. The kernel from the 3.0.1 update is still in effect.

What gives??!?!

Maybe I should try the tiamat kernel instead? Whats the difference?
[Xoom Android Development] stigmax:
kjdocs. The stockimage link still works.
[Xoom Android Development] drawde:
Considering doing this too.. OC is cool but to be honest I didnt see any positive difference outside of linpack / quadrant or other benchmarks.. What I hated the most was the slowness of the home screen which I dont have with setcpu off.

Not taking anything away from what you've done but its just not for me right now.
[Xoom Android Development] Neo3D:
Can someone please run this Flash Benchmark:

http://www.themaninblue.com/experiment/AnimationBenchmark/flash/

And let us know how much Flash improvement we get with the various o/c speeds?

My main interest in o/c would be to get Flash performance on the Xoom closer to netbook or laptop Flash performance.
[Xoom Android Development] jparker36:
Desktop PC: 110fps (i7 930 @4Ghz, GTX 480 @850/1000/1700)

Stock 1Ghz - ~32fps

1.2Ghz - ~34fps

1.4Ghz - ~36fps

1.5Ghz - ~37fps

for lulz:

456Mhz - ~18fps
[Xoom Android Development] Neo3D:
Thanks! It doesn't look like Flash Player 10.2 for Honeycomb is fully utilizing the CPU the way it does on desktop. Flash is designed to fully take advantage of multiple cores:

It's interesting that we only see marginal improvements with the speed bumps though.
[Xoom Android Development] iTablet:
Ok I think that test depends on browser render performance.

Tried with firefox 4.0 : 37~40fps

Tried with IE9: 86-91fps

Same Computer T6600 No OC.
[Xoom Android Development] nswenson:
coolbho3000, thanks for putting this kernel together for us. For the most part it works pretty well for me. One thing I did notice is that although I've limited the CPU to 1400 in SetCPU, the CPU is still jumping to 1504 on occasion. I think this is causing a bit of instability for me when running heavy flash video and rich web pages. If you have time, could you please compile kernels with lower max settings. I think one with 1400 and one with 1200 or 1300 would cover most people. I think it would really help with stability for those of us with marginal CPU's.
[Xoom Android Development] Droid-Xer:
JRummy's overclock app is xoom compatible now. I think its easier to use his app and run setCPUs profiles.
[Xoom Android Development] aohus:
how are you able to get his app running on the xoom? i updated to latest 2.1.2, but it keeps saying i don't have root when i do.
[Xoom Android Development] Droid-Xer:
Thats the latest version. Do you already have an overclocked kernel flashed? The app won't overclock unlocked devices, its just a nicer interface to adjust settings. there are 11 vsel slots to set
[Xoom Android Development] aohus:
where can i get the overclock module? thats the only thing im missing to get all overclock capabilities in jrummy16's app.

how would i get the module? and how would i go about installing it?

thanks in advanced.
[Xoom Android Development] jmc2543:
OK I asked in the general section and had 66 people look at my post and not one answer. Is there any way I can get the stock kernel for 3.0.1 or is it the same as 3.0? I want to flash the OC kernel but want the option available to go back to stock if I want to.
[Xoom Android Development] Droid-Xer:
In the dev section Theresa the tiamat kernel or setCPU kernel. Install instructions are in those threads.
[Xoom Android Development] techs1200:
I'm having a problem with the OC kernel since updating to 3.0.1

Well actually its a problem with setcpu.

When my xoom goes to sleep it will ignore the setcpu settings and down clock to 216 mhz. Problem is, it gets stuck there unless I open the app and move the sliders.

I previously had both min and Max set to 1.5ghz and it worked great, even when sleeping it would stay on 1.5, battery life was still great too...

I have tried both interactive and performance governors in setcpu, problem won't go away!

Any ideas? Do we need a new version of setcpu?
[Xoom Android Development] Droid-Xer:
Set up a profile in setCPU for when the device is on standby
[Xoom Android Development] techs1200:
Tried that. Still downclocking to 216mhz :-(
[Xoom Android Development] wnrussell:
Before and after the 1.5 GHz kernel

I usually run Quadrant twice and use the second reading. It seems more consistent like that.
[Xoom Android Development] moobies:
Thanks

This looks great! I can't wait to oc.
[Xoom Android Development] jmc2543:
Ill ask again in case my question is lost. Can we get the 3.0.1 stock_boot.img. Please and thank you.
[Xoom Android Development] xlGmanlx:
Did you autodetect the kernel again?
[Xoom Android Development] ChongoDroid:
Isn't that just putting extra miles on your processor for no reason at all...

[Galaxy S I9000 General] hiveNzin0:
Hi,

I don't think it's Galaxy S related so if it's the wrong place, it would be great if someone could move it to Android general.

So, I own a Samsung Galaxy S (international) and a micro SD Card Kingston. This morning, I tried to modify my GS (get root access, use voodoo lagfix, ...) and now, I have a problem.

When I start the GS, everything works fine, I can see my SD Card and my music on it. If I connect the GS on a computer (Gentoo or Windows, doesn't matter), the OS doesn't detect the 32GB SD Card.

When I turn off the USB connection, my SD Card disappeared, I can't access it from the GS anymore.

I have the external SD Card that is a perfect copy of Internal SD Card (~6GB) => Settings -> SD Card and phone storage.

If I want to get access to my 32GB SD Card, I have to reboot my GS.

By the way, I did a backup with MyBackup (I removed the 32GB SD when i did that) and the app copied the backup in /mnt/sdcard/external_sd which was empty.

So now, here is the /mnt/sdcard/external_sd :

Boot (32GB activated) :

/mnt/sdcard/external_sd = 32GB SD Card content (music, movies, ...)

After connecting the USB and change the GS as mass storage device :

/mnt/sdcard/external_sd = MyBackup's backup (6GB content).

Another thing, If i reboot the GS and connect it to kies (not mass storage), I can find my 32GB SD Card and when I close Kies, it's still okay in the Galaxy S, I can still use my 32 GB SD Card.

It's strange.

Can someone help me with this ?

Thanks.
[Galaxy S I9000 General] erkv:
I had a similar problem with my sgs some time ago with stock rom. Samsung support suggested me to hard reset.

After flashing a new firmware everything worked flawlessly.

Kies might be the problem.

Dont know a lot anyway.
[Galaxy S I9000 General] hiveNzin0:
Hi,

thanks for the answer. I'll try another ROM.

Btw, I read that Gingerbread is coming out in March. If I use a custom ROM (Darky 9.2, Insanity, CM7, ... whatever), could it be possible to get the Samsung Update (after a factory reset for example).

For the moment, I have a voodoo lagfix with recovery mode (e2). Could it be broken after the update ?

Thanks.
